mdd: True, but I was taking “unaffiliated” at face value. Of course, if the people already identify with, well, I guess a way to put it could be Judaism as opposed to Yiddishkeit, then your job is made a lot easier.
It’s if Judaism is an absolute nothing in your life (as was my probably unfounded assumption) that you’re REALLY in trouble.
Once one has some form of Jewish identity this all becomes a lot easier.
